IMPROVEMENT IN HEELS FOR BOOTS, &c.

Specification forming part of Letters Patent No. 143,685, dated October 14, 1873; application filed December 30, 1870.

. To all whom it may concern:

Be it known .that we, `JoHN B. GERHARD and CHARLES Cr. SCHWARZ, both of the city of Philadelphia, in the State of Pennsylvania, have invented a new and Improved Heel for Boots and Shoes; and we do herebydeclare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference thereon.

Our invention consists of a heel for boots and shoes, Ste., made of glass, porcelain, or other vitreous or cremaceous material, l and constructed so that it can be readily and securely attached to the shoe without danger of being' broken either in application or use.

The heel D may be cast or molded, the eX- terior form depending upon the character of the shoe and the prevalent style, a ilange, d, which becomes narrower and gradually merges into the heel toward the front edge, forming a cuplike bearing for the rounded rear portion of the sole B. In the top of the heel is a recess, E, adapted to receive a corresponding projection on the sole, and in the bottom of the heel may be a short socket or recess, H, for a lug or projection, t, on a rubber cap, je, which corresponds in form with the lower face of the heel. In the projection tis embedded a metallic nut, s, adapted to the threaded end of a bolt or screw, o, which extends through the sole and through an opening, a, in the heel, its

head resting in areoess in the inner face ofthe sole. The bolt securely retains the heel, while the projection c on the sole resists all lateral strains orjblows to which the heel may be subjected, thus relieving the bolt and preventing it from working loose.

The retention of the bolt andthe security of the heel are further insured by embedding the nut s in the rubber, which yields slightly, per mitting the nut to rise, but maintains it so irmly in contact with the bolt (acting as a lock-nut) that neither can turn. The rubber cap 7c furthermore clamps the heel iirmly without the danger of breaking it that would result from employing a cap of unyielding material, while itl also serves to deaden the sound and reduce the danger of fracture when the heel strikes a hard substance.

A heel of glass7 or its equivalent, is superior to ordinary molded heels, from the fact that it can be manufactured, at a nominal cost, from waste materials. It may be made of any desired form, in molds costing but a few dollars, while the composition heels madeof waste rubber, 85e., can only be produced by the use of heavy and expensive machinery for disintegrating and mixing the waste and condensing the same under enormous pressure in the molds.

Vithout confining ourselves to the form of heel shown, or to any special mode of securing it, we claiml. A s a new article of manufacture, a heel for boots and shoes consisting of glass or its equivalent, and adapted to be applied and secured as set forth.

2. The combination, with the heel, of an elastic cap, 7g, between which and the sole the heel may be clamped, as described.

3. The cap k, applied to the heel and having a nut, s, embedded in a projection, t, for the purpose set forth.
